Works as advertised.

Its exactly what it says and works perfectly !

very awesome for videos too loud or too quiet and I couldn't notice a quality drop unlike most boosted volume apps/add-ons! Very nice.

The only sound booster add on that works perfectly.

It does it's job, exactly what it says and it's great! I am satisfied however, if the UI had some sort of design, it would be much more pleasing to look at. I don't have anything else to say about this though!

It works amazing. It would be nice to not have to set the volume again every time you open a new tab. Other than that it's a most have!
